Chelsea chief executive Peter Kenyon says any problems from last season have been resolved - on and off the pitch.

Owner Roman Abramovich and manager Jose Mourinho were reported to be at loggerheads and Manchester United beat Chelsea to the Premier League title.

But Kenyon said: "I'm not saying there weren't issues, there were various issues - as there are at every club.

"That has been addressed, I'm confident about next season and I don't think anyone wants a repeat of last year."

Blues landed a domestic double by winning the Carling Cup and FA Cup, they failed to retain their league crown and were knocked out of the Champions League by Liverpool at the semi-final stage.

Having signed Andriy Shevchenko and Michael Ballack to boost their European hopes, that defeat at the hands of the Reds was particularly painful and Kenyon has previously described reaching a Champions League final as the "holy grail".

There have been discussions ongoing, they have been good discussions and carried out in good faith by all parties

But he believes Shevchenko and Ballack will shine this season after struggling following their high-profile arrival 12 months ago.

"Andriy and Mike came in on four-year contracts, not for a year and then if you do OK we'll re-sign you," stated Kenyon.

"It's a four-year commitment to add value to the squad over a period of time.

"Both of those players know they have got much more to achieve and want to achieve much more.

"I remember having a similar conversation this time last year. It can be easy to underestimate settling into English football."

The Stamford Bridge outfit have already swelled their ranks for the new campaign, with the signings of Steve Sidwell, Claudio Pizarro and Tal Ben Haim, and they are confident of landing midfielder Florent Malouda from Lyon.

Plus, Glen Johnson has returned from his loan spell at Portsmouth and Chelsea are confident that work permit problems will be resolved so defender Alex will be available after a loan period at PSV Eindhoven.

Kenyon also has high hopes that England international duo John Terry and Frank Lampard will sign new contracts, although he refused to put a timeframe on the conclusion of such negotiations.

"If you're asking me 'would it be nice to get it done next week?' Yes, it would," added Kenyon.

"There have been discussions ongoing, they have been good discussions and carried out in good faith by all parties. I've got faith in the players' professionalism not to let it affect the way they play.
